Cast iron is an iron alloy containing 2 wt.% - 4 wt.% carbon, 1 wt.% - 3 wt.% silicon and smaller amounts of minor elements [1]. In comparison, steel has a lower carbon content of up to 2 wt.% and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.

The solid content of all slurries was kept between 24 and 26 wt%. LNCO powder and carbon were mixed in zirconia jars by a planetary ball mill at 150 rpm for 10 min, followed by a 5 min break and another 10 min of milling. Subsequently, the polymeric binder was added and mixed with an analogue procedure.

It is produced by making that portion of the mould—where the white cast iron is desired—of a material that can extract heat very rapidly, such as iron or graphite. In some cases the castings are designed and produced to have a white structure in certain areas and a grey or flake structure elsewhere to improve toughness.

Shiploading applications use Dust Solution's unique DSN-12 nozzles, which are the most powerful nozzles in the range. These give a good projection and volume of dry fog which means that the large open area of a ship's hold can be tackled with Dry Fog, creating the fog blanket which dust travelling up the sides of the hold will not penetrate.
